I've spent many hours reading and doing research about this. I don't attend any university classes or any type of classes that may approach such a topic. I am trying to learn this by my own without ...

I've been a C++ developer for 10 years. Quite high level. And I am completely new to Digital Signal Processing.
I am trying to implement a Software Defined Radio. Specifically I am trying to receive ...

As a learning exercise, I'm trying to reverse engineer the radio protocol of a 27MHz wireless mouse. The device currently transmits on the 27.045MHz channel and uses 2FSK. I have an IQ recording of ...

I have two radios sampling simultaneously, and I am trying to time-align their two signals (they will always start sampling at slightly different times with random delays due to hardware differences). ...

How can software-defined radios operate at high frequency?
The Nyquist rate dictates that you need to sample at twice the frequency to fully recover the signal. If my signal of interest is modulated ...

In the seventies I worked for Muirhead on press fax machines that used to transmit pictures over radio and landline as I recall two FM systems were used a carrier 800 Hz modulated +- 150 Hz and 1900Hz ...

Most likely a very simple question, but I haven't been able to find a good answer.
When working with analytical signals in general, and software defined radio in particular, a common operation is to ...

I want to know what methods are best to scientifically evaluate the quality of different Software Defined Radios (SDRs) that spit out IQ samples.
For this question, I would like to set the boundary ...

I am interested in knowing whether BladeRF SDR with a frequency range of (300 MHz - 3.8 GHz) detect AM and FM frequencies? Also, how important is the sampling rate of the SDR. For example, BladeRF has ...

I am having a hackrf-one device which can either transmit or receive signals. I am having a GNU radio flowchart which has a selector block which allows manual switching.
I am not able to switch it at ...

I posted a similar question a while ago here (I'm posting this follow-up since I'd like to focus more on cross-correlation now). I have a setup where I have two software-defined radios connected to ...
